Organic electroluminescent device and method of manufacturing the same
Abstract
The invention provides an organic electroluminescent device and a method of manufacturing the same which conveniently reduce or suppress the transfer of ionic impurities into a light-emitting layer, and reduce or prevent the light-emitting property in the light-emitting layer from degrading, which promotes life extension. An organic electroluminescent device includes a functional layer having at least a light-emitting layer between a first electrode and a second electrode. At least a part of the functional layer is formed of the inorganic ion exchange material added to the functional material to form the functional layer.
Claims
exact text as granted — not AI-modified1. An organic electroluminescent device, comprising:
a first electrode;
a second electrode; and
a functional layer having at least a light-emitting layer and a hole injection/transport layer between the first electrode and the second electrode, the hole injection/transport layer including a hole injection/transport material and an inorganic ion exchange material.
2. The organic electroluminescent device according to claim 1 , the inorganic ion exchange material being antimony pentoxide hydrate.Join the waitlist — get patent alerts
